Abstract
Transaction cards operable as 'smart cards'; credit cards; debit cards; access cards; et cetera, having an self-enabling and self-disabling feature provides for authentication and proper user verification. The card receives input from a user and determines if the input is valid. If the user input is valid, the card responds by enabling a magnetic stripe thereon. The magnetic stripe is enabled for a limited time after which it is then disabled. A disabled magnetic stripe is then inoperable for activating card readers. A card which is lost or stolen cannot be used by unauthorized users as it would have a magnetic stripe in a disabled state and only an authorized user would have the ability to enable it. The card possesses a high level of compatibility with known methodology in the art and does not require additional equipment and systems to attain its high security level.
